Amazing what new gas and plugs will do!
I drained the old gas and decided to replace the Bosch +4 with NGK TR6 (possible NOS system in future).
What a difference!
No more WOT miss! Smooth, fast acceleration! Just like it used to run before it was parked for a year!
I also replaced the gas gap which didn't meet the pressure test. Now I'm ready to go pass emissions! I got a tip to drive it for 20-30 min to get the CATS heated up which should help get the high-lift CAM to pass the HC standard.
I'm going to also get it dynoed on Friday and I've ordered an ALDL cable to go with the DataMaster software to get some scan numbers. I'll then send this to Ed Wright at Fastchips to get my PROM updated. And finally go to the track and see if I can still run high-11's in the heat or possible mid-11's.
